What version of Go are you using (go version)?

$ go version
go version go1.13.5 linux/amd64
$

Does this issue reproduce with the latest release?

Run $ go help testflag and see the lack of explanation for -race flag.

What operating system and processor architecture are you using (go env)?

What did you do?

What did you expect to see?

I'd like to see the explanation of "-race" flag to know the behavior.

What did you see instead?

I cannot see it.

It's in go help build, which you can see mentioned in go help test:

For more about build flags, see 'go help build'.

It's a build flag, not a test flag, so it doesn't belong in testflag.

@mvdan Thanks for your explanation, I got the meaning.
@cagedmantis Yes, @mvdan's response is good for me, it is fine to keep this as closed.

Thanks for your help :-)
